[Sony Tablet S] fortissimo:
I am sorry that it took 2 weeks for me to reply to this thread. Is that a problem? I do not know that a prompt reply is required on a public forum?

To me, "not applicable" means "not doable" because your post did not make any elaboration beyond a one line comment, however critical this info is. But regardless, to give you the benefit of the doubt, I simply asked you one more time to give you a chance to explain further. But you came back with an answer about unlock code, and nothing about what was about the response you made to the other poster, about F5521gw.

And of course I am talking about the Sony Tablet P marketed by AT&T, the 3G version, which I own. The question by the other poster, is about a Japanese version, but regarding swapping the modem card, the process is the same.

The thing is that how hard it is to change the modem card should not be a question to me, but rather to cdwangxd since it is he who suggested it, but why didn't you ask him about this earlier on? But questioning me now about this, as I am not the person suggesting it, but the person questioning your answer about "not applicable" and wanting further information and clarification.

I don't know the schematics of this device, but do you? If you don't why did you claim it is "not applicable", in which and what way?

Not only others have mentioned about replacing F5521gw cards on various forum posts (forgot which forum at this point), I have opened up my device and can confirm that it is a F5521gw card which is (naturally) removable from its m-PCIe socket. And it is not soldered on the main board.

And as for who would do it for you and for how much, this is rarely a question on xda here. Most xda members prefer to do things themselves and some are more hardware savvy and some are less. It took me a 2nd try to find the edges to pop out the top cover, but it is not that hard. Granted I have some experience in hardware so I am not suggesting everyone trying the same thing. Again, I am not the person who suggested swapping the card, so I am not sure why you are directing the risks and dangers (possible) to me instead of cdwangxd who suggested this (whom you did not say any of these for those times).

I have put back the original modem now, but if I have another one (let's say an unlocked generic one) in front of me now, I can swap the whole thing in 10 minutes, start to finish. So may be this is not easy for some, I am sure some people including myself, can do this.

The problem here is your sense of logic. It can make our debate difficult. Let me make an example:

1.cdwangxd said the sun rises from the east.

2. you came back saying that the sun does not rise from the east (basically my interpretation of what "not applicable" means without any other substantiation, which you still failed to refer back to what you mean. And I am sure you mean "no" basically.)

3. I asked if you have any back up saying that the sun doesn't rise from the east, surely I have some doubts but want to give you a chance.

4. You came back saying that since I don't have proof that the sun does rise from the east, then I cannot question your response.

So in your logic, the sun does not rise from the east only because I cannot provide proof. Where is your logic? For anything you state, the onus is on you to proof, not for the one questioning it, as that'd be "begging the question" if not more paradoxical.

My intent is simple and pure. cdwangxd has a suggestion that I have also read about elsewhere, but there hasn't been a reported case of success. Moreover, there are various models of F5521gw on eBay, some are named generic, Dell or HP, and some claimed generic are actually Dell. It is important to find out what works, before buying as it is rather hard to return for refund over eBay. Other sources are more expensive, and usually foreign and thus, also hard to return.

I put that question out to you, because cdwangxd provided a method (which I have read elsewhere to be same), that is plausible. You brushed it off with a one liner, which could be the most critical part. If you are right afterall, then there is no need to go shop for a F5521gw, saving the money and effort. So your response is deemed critical and thus I have a valid reason of wanting a confirmation.

But you prefer to beat around the bush, questioning everything else, including putting the onus back to me, instead of answering the question: why did you respond with that line? Under what kind of information have you gotten and if you are prepared to share.

My delay in 2 weeks doesn't mean the truth can be altered. If it works or not, 2 weeks does not make a difference. Please stop having excuses after excuses.

And last but not least, since you did not even know for sure if the modem inside is F5521gw, removeable or not, how dare you said that cdwangxd's suggestion is "not applicable"? It is beyond that you have read wrong info about this, it is that you simply didn't even know until now (as I said earlier here). You simply had as much as a guess, but you put the line as short and abrupt (end all and be all). So basically my original calling you out on this, isn't far from what I suspected: you didn't know what you were talking about, simple as that.
