[JASJAR, XDA Exec, MDA Pro Software Upgrading] Churchill:
OK boys and girls...

I have tryed the O2 ROM the whole day yesterday and last night late reverted to JasJar ROM. Reason: maybe I did something wrong but in corporate install of the O2 ROM with the code 0506 but I had no pdf reader which is unfortunately a crucial software for me. I have tried to install it from the cabs of the O2 ROM and from JasJar ROM but it would not work. Of course the solution might be to get a cracked version. But that fact pissed me off so much that I have loudly cursed O2 and reverted to JasJar.

Observations: I have noticed that O2 ROM has more program memory when you reset the device but once you use the thing the amount of program ROM is the same as in JasJar. So the fact that just after the soft reset there is more ROM is actually not interresting. I also found that in the O2 ROM there is a problem with the start menu opening up first time after a soft reset (If you soft reset the device and then for the first time click on start it takes 10-13 seconds to open it up) and this issue was the biggest issue for me to change to O2 ROM. Pocket MSN seemed to work faster and is more responsive on the O2 and maybe overal performance is a little notch better then JasJar. The Bootup Splash screen on the O2 is much nicer then on JasJar it is really sharp and cool :)

Conclusions: If you like experimenting try out the O2 ROM because you get to see also (if you try out the Personal install) how badly an operator can F*** up the device, it is beyond my understanding but it is hideous their Launch software, the screen looks like a battle field and I get dizzy looking at it, the task manager which it installs is such a crap only due to a fact that once you close all the progs with the task manager the task manager is still running so to close it too you have to go to settings ->system->memory and close it from there. I can understand that the task manager which you can use from your today screen has to be running in order to work but this task manager you have to start by going to programs and starting it manually, It is comepletely beyond me what is the purpose of such a task manger, but hey maybe I am STUPID ???

The battery icon moved next to the start I can understand the handyness of this, but the O2 icon which does not do anything is also comepletely beyond my understanding. Plus when changing the screen orientation the battery and the O2 icons suddenly get a darker background and it looks like it hangs, but it only looks like it the device does not hang, but it is still an ugly sight to see...

If you opt for the Corporate install with the 0506 code I think you are fine the machine performs as it should, and is very stable, no O2 annoyances and no O2 **** to be seen apart from a couple of icons in the Programs. One of them is the O2 install which I beleive supposed to allow you to change your install type, without making a hard reset, but of course it only works in one direction, meaning that if you have a corporate install with the code 0506 and you want to change to standard or to personal it will work but if you are running the standard and want to go back to corporate or if you are runnning the Personal (full featuer O2) and want to change to standard it will not work. After playing around with that I have found that my simmanager and enroller icons dissapeared, but I was able to get it back by running one of the cabs. it was different with the pdf reader, since I need one I have decided to run that O2 install type thingy and chose first standard install which did not bring the pdf back, and then I have chosen the personal install which would mean that I should have now everything on it , the pdf icon was there but alais the pdf did not work I kept on getting an error.

One more thing when you install the CORP version the dialer skin is the same as by the JasJar so I beleive that that is the generic skin, since the O2 Dialer skin is very vague the buttons are beautiful, but have to much light in them so it is difficult to see the letters

SO I am back to JasJar ROM and I beleive will stick to it for a while.

The progs I run :

TT5.1

Resco Explorer

Skype 1.2 beta

Backgammon

Total commander

All installed on the storage card

I hope this not too boring and helps folks here.
