Is anyone aware of an alternative (with a similar budget price, maybe something marketed in the developing world?) that can be used on a modern phone network?
The Kyocera Rally is another 3G candy bar feature phone with more of a budget price ($20 from Amazon but locked to T-Mobile).
I have a Sony Ericsson K850i that's quadband GSM and works on HSPA 850/1900/2100 (meaning it'll work on AT&T and T-Mobile's 3G networks as well as a good chunk of international 3G networks)
