You might reconsider since the choices are somewhat tepid of late. Personally, I would consider buying an unlocked, unbranded, non-ATT issued smartphone since you will likely be spending at least $100 anyway for a basic phone that doesn't do very much. I certainly wouldn't expect much from their free to $50 range of non-smartphones as upgrades. Heck one of those replacements likely won't even get the same reliable reception as your current taped RAZR. Also, unlimited data on a 'dumbphone' with a tiny screen makes little sense in this day and age. And yes, you *can* use a smartphone on ATT's network w/o having to change your data plan, btw. One of the following Nokias would fit the bill nicely IMHO and E.
Nokia C6-01 (true, worldphone with all the GSM & WCDMA frequency bands), includes HD capability
C3-00 (least expensive, but lacks 3G frequency bands)
I've dropped my Razr V3xx for the last time (RIP). I am looking for a unlocked, non-smart phone - I have an unlimited date package with AT&T right now and don't want to be forced to switch to pay more. I mainly use my phone for taking & sending pics, text messaging, and internet access. I want to download ringtones, store mp3 if possible (but not required) and play games. Oh yeah, I also use it for phone calls. I am currently using my 5 yr old duct-taped Nokia as this is the only phone I have so I need advice asap.
