I have recently bought the new Samsung Admire (Metro PCS) and have yet to receive a 3G signal. I have been reading up on this online and have come across several blogs about people "rooting" their phones to somehow update the PRL number of 03019 to 03022. I am completely new to this sort of thing and was wondering if there was some way someone could guide me in the direction of doing so. Also, when I first took this phone home, I noticed that the battery life was VERY bad - but have again read articles online to help with that and I believe by following some of the steps pointed out to increase battery life, I have done just that. I was wondering also if not having data enabled would cause me to have no signal.. I am able to make phone calls and send/receive text messages, but cannot browse the Web (Opera Mini). I usually have low signal at my job, so maybe today was just one of those non-signal days. But not having data enabled has definitely increased my battery life by a long shot. Any tips/tricks would be greatly appreciated!
