My wife is switching from Verizon to my T-mobile account so we can share minutes. She wants an old-technology phone since she only uses her cell phone for voice calls. She requires a small phone -- under 3.5oz and less than 0.6" thick. She likes the thin clamshell designs, but would consider a bar phone.

Using the awesome search engine on this site, I came up with a short list:

Nokia 5130
Nokia 5310
Nokia 6300
Samsung T519
Ericsson Equinox
Moto RAZR V3

As usual, the reviews are mixed, but I can ignore issues related to texting, internet, music, camera, speakerphone, etc. Reception is important. Less so battery life. Any thoughts?
