Not keen on the ridiculous roaming charges.
So, looks like the top contenders for me (from what I've read so far) are - prices in USD:
(1) Straight Talk - $45
(2) $30 T-Mobile Prepaid
Leaning towards Straight Talk for iPhone 4 (and maybe iPhone 5 as well, although apparently $30 T-Mobile Prepaid works wonderfully on iPhone 5).
Anyone had experience with these plans recently? (especially in Los Angeles, particularly the Santa Monica & Anaheim areas?)
