USA cell phone service totally sucks.
I get excellent high-speed Internet service from the 3rd-world for about $20 a month UNLIMITED (1+ mbps). From the rice-fields in Thailand I can get WCDMA, GPS/GPRS. The phones are the same Nokia/Samsung/motorola,etc you can get in the rest of southeast Asia/Europe - n95 for example. The providers are 1-2-GO, AIS, DTAC, orange, etc. AND NO STUPID SERVICE PLANS. You buy the phone at a PHONE STORE (thousands available), then pick a service (the SIM card), then re-fill used minutes at any phone store, 7-11, or online/automated. Most people(there) don't bother with more costly DSL/cable modems. Their PCs get high-speed internet from the cell phones via bluetooth.
Like I said, the States has sub-third world service.
my 2+ cents,.
