I've always given AT&T Tilt great appraisal for its loaded functionality and spec (3.5G Asia + Europe and US, Wifi, GPS, WM6, etc...). I've seen its price on Amazon fluctuate from as low as $49 to $99 to $174 after rebates. As of this morning, they are going for $249after rebate on Amazon.com. Its still a deal considering that the phone itself is priced at $600.
It is unusual to the cost of a subsidized phone that is going on its 7 month on the market to go up when all other phones are being lowered. If you are seriously considering this phone, you might want to see a limited discount of the N95-4 8GB US editionfor a mere $579 (MSRP $799).
