Hi, all! I'm coming from AT&T, my contract is up and I'm switching to T-Mobile on a family unlimited talk-text plan. I most definitely will not have data. I'm considering this LG Optimus T very much; it's got fantastic reviews, Wi-Fi, and is free because of the promo! I really just wanted a durable phone with Wi-Fi, Bluetooth, and decent messaging capabilities. Any cons to speak of? If so, in light of my data plight, above criteria, and T-Mobile(ness), any better options? Also, what do rooting and overclocking your phone do? Cons? Can this phone handle it? Lastly, (sorry about all the questions), I have a specific question about the "lock" feature on the phone. Thanks in advance!
