I was just about to go with a w800 but i recently found out about the w810. Is there a huge difference between the two phones? Should i go with the w810 instead?
Ther are not any major differences between the two, just some minor improvements on the W810i. The biggest issue is that the W810 has 850Mhz, while the W800 doesn't. This depends on where you live and if 850Mhz predominant in your area. If you're going to use it in the US, then definitely the W810.
W810's can be unbranded too. I also set mine to get rid of that annoying camera sound. Even though the camera sound still forces you to choose a sound, it's not heard if you have the camera in silent mode.
