Amazon.com has a bunch of cell phones that make you lots of money after rebate. The following phones I list make you the most money, but there are many others. I bought a phone from Amazon about a year and a half ago and the rebate process was quick and easy. You might have to hurry because a lot of the rebates expire 12/1.
Sony Ericsson T610 Phone (T-Mobile) makes you $175 after rebates!
Sony Ericsson T637 Phone (Cingular) makes you $140 after rebates!
Sony Ericsson T637 Phone - (AT&T) makes you $200 after rebates!
Motorola V300 Phone (T-Mobile) makes you $100 after rebates!
Samsung E105 Phone (T-Mobile) makes you $125 after rebates!
