I converted my prepaid line at the local Alltel/ATT store and chose the LG CF360 slider phone. The phone was $20 + tax, $15 of that goes on the new go phone account along with the remaining Alltel U account balance.

When converting you can choose your go phone rate plan.

Other phone offered were a Pantech qwerty phone for $50 and the next phones up were around $100+.

Phonescoop shows the CF360 as discontinued. I am fairly happy with the phone, it gets good reviews, feels solid and has good rf performance. I put my post paid sim in and the phone worked fine. I was told that once the phone is turned on with the prepaid sim inserted it locks to that sim or prepaid only sims. Im not going to try it.

Expect long wait times at the store when its conversion time in your area. If you dont have a few hours to burn, go another time. The store was packed with phone book transfers, exchanges, plan mods etc. It is simply please sign in and please wait to be called.

This was my experience with prepaid conversion/retail store, no doubt phone selection and procedures will change.
