I just purchased a blackberry after my G1 got soaked (rip )
Anyway, i'm running OS 4.2 on it, and I desperately need to be running 4.3 or higher. Since T-Mobile doesn't officially support the 8300 i can't upgrade through them.
I'm been googling and googling, but i cannot seem to find a suitable answer.
This is my first post, (but i even searched the forum and didn't find my answer)
i saw the sticky and it said east asia and a different carrier.
i called t-mobile today and they were very helpful. they said if you have an unlocked phone, then you need to use the update that is issued by that carrier... so in my case i have to get the updates from at&t even tho i am using t-mobile's service.
