LG...Live is Good.
They make my prepaid Tracfone...buy it at Radio Shack along with time cards for sevice,Wallmart may have a better deal.
You can also get the Virgin Mobile there and it is alot cheeper and if you put $20 on it every 90 days all unused time stays with you as well...$19 for phone and first 90 days (again see Wallmart).
