Top message: This is the flip phone to get by Tofuchong
Replying to: 3G by Rich Brome
T-Mobile only has one 2G only phone on their website for post paid customers to purchase, ONE! and its a refurb Nokia X2 and its FREE. This device was introduced as an upgrade to a 2G only handset so they are definitely moving away from 2G only devices on post paid lines. Plus I am sure customer service would help you with a free upgrade to an 3G compatible handset if you are still clutching your 2G device come EOL for the 2G network.
On the prepaid side they have 4 but given the average cost of those 4 devices ($49) I highly doubt it will be the financial ruin of anyone if they have to switch their handset when they finally get around to sunsetting their 2G network say in 2017 (see AT&T).
Quit being so dramatic!
