hi i am using the lg100c for last 6 month , it's very simple phone . so i want to buy good phone with music option and with a good camera option . and right now i am looking at sony ericsson w995i. i feel it's very nice phone for me. but the problem is right now i am using the straight talk provider . so can i use the phone with the same provider ? i mean my phone number will remain same if i use the phone ?
