Hi all! New User to BB here and just wondering...

If I do one of these OS upgrades and am on AT&T network, will my BB keep all its icons and such?...Media Net, AT&T Music, etc...?

Wanna make sure everything will work before I go ahead and make the jump, seems like a lot of people are happy with the upgrades, although not too sure what advantages it has vs. factory...

Thanks and sorry if this question has been asked before...

No, an OS from another carrier will not retain those carrier specific icons.

To keep the functionality of your BBerry, I suggest you only upgrade your OS to whatever your carrier provides.
