[Touch HD General] guney:
I've had very bad luck with using my Gmail account on my new Touch HD so far. Anybody else had problems with this?...

Here's what I've observed:

I've installed the Gmail Java client but haven't been able to login to my Gmail account with it even once. It fails to sign on every time, saying "this program requires a working data connection". Of course, I'm sure that I'm using the correct user name and password. I've also tried entering just "username" into the first field rather than "username@gmail.com". Didn't change the result. Meanwhile, I can connect to the web via Opera Mobile and Opera Mini just fine and use other network-enabled apps like Google Maps. So, I do have a working connection. I've also tried turning off my data connection so that it's established from scratch on the next attempt. It didn't help. Turning on airplane mode for a little while and then turning it back off to try again didn't change anything either.

I've set up Gmail as an account in Outlook Mobile. Initially, I just used the automatic setup. It worked fine at first. It downloaded an initial set of that day's e-mails. I'm pretty sure a later send/receive also retrieved an additional messages even. But it stopped working at some point after that and, ever since then, this Outlook account hasn't worked either. It keeps showing an "error synchronizing" message on the status bar and I get a pop-up saying "cannot connect with current connection settings". There's nothing wrong with my connection settings, as I explained above. I try a website (that wasn't cached) on Opera Mobile immediately after this and it comes up fine. I've also tried a warm reset, but it didn't do anything. I've then deleted the Gmail account and created it from scratch using the manual approach explained here and on the Gmail site (starting with "g@g" as the fake address, and so on). Still, no go.

Meanwhile, I can login to my Gmail account via Opera Mobile on the same device (or from any desktop machine) just fine.

This is only the second day I've had this device and I had spent last night installing a bunch of applications on it (which I'm accustomed to using). Some of these were networking-related applications, too. However, I'm pretty sure that my Gmail account in Outlook Mobile was set up and was (temporarily) working after installing all those apps. So, I don't see that much chance that something I've installed might be causing the problem. (But I'll still try a hard reset and start from scratch as a last resort, if I have to.)

Is anybody else seeing anything like this? Specifically anyone who's using the Touch HD on AT&T's EDGE network, perhaps? Because, I'm beginning to wonder if I should suspect some weirdness about the network. That is partially because I also noticed another strangeness last night: The white square background of the "E" logo for the EDGE network on the Touch HD turned from a solid white to a "cross-hatch patterned" or "faded" appearance for a few hours. During that time, I couldn't connect anywhere at all. I tried a few things and some resets, but nothing changed it. That was the status last night as I went to bed. This morning, I woke up, and the logo was back to normal and all connections (with the exception of Gmail) worked fine again. So, that's why I think that strange logo was due to an AT&T network issue. Assuming that one was an AT&T screw-up, I'm now wondering if another more minor AT&T network screw-up might still be at play that prevents me only from connecting to Gmail. (Something specific to SSL connections, perhaps?...)

Incidentally, after typing the end of that last paragraph, it occurred to me to try an SSL connection. I tried the web-based mobile login page for Gmail in Opera Mobile once again. (It uses HTTPS.) It worked fine. So, it can't be a fundamental problem with SSL connections either.

Or could Gmail be experiencing some short-term anomalies with their IMAP server at the moment? Anyone seeing anything like this with them at the moment when using IMAP?

I'm completely stumped. I can't even imagine what else might be going wrong.

Any ideas as to what I should try next?
