Samsung U550 is for Verizon
This article contains unofficial information.
We were provided with several spy-pictures of the Samsung SCH-U550 today. Little is know about the phone at this point, except that it will be released by Verizon Wireless in the early 2008 and will replace the current U540 as a mid-level phone. Our guess is there's not much hardware change here, with mostly only cosmetic upgrades.
