Can someone help me, I have an unlock AT&T 8310 and wanted to upgrade from an OS of 4.2.2 to an 4.5, my provider is T-Mobile. The only download link that I see is from Vodafone....I'm in Pa., I'm afraid to install for fear of messing my phone up. Any suggestions

Have you checked BlackBerry.com?

You can use anyone you want as long as its compatible with your berry whatever model it maybe, delete the vendor xml file and your good to go.

however if your just gettin your berry, i would give it sometime get to know it and then go through upgrade process

Well my first suggestion, and yes I'm assuming you are new to Berries, is do not attempt to run beta software on your newly acquired Berry. You may be asking for heartache.

Second, if you simply must, there are several threads dedicated strictly to running 4.5 that can step you through the process.

Tmobile just released the 4.5 yesterday. If you log in to your account on tmo's site, you can find there.

I am having troubles with my upgrade, but the new features are REALLY nice!
