The i8910 HD runs the Symbian operating system, and we think it does a much better job of it than Symbian's biggest champion, Nokia, did with its touchscreen effort, the N97. The Omnia i900 runs Windows Mobile 6.1, which makes us feel sad inside due to its tiny, tappy icons.
Both phones support installing your own applications, and there are tonnes of great ones out there for both operating systems, but finding and installing them has been no easy task in the past. Nokia's solution is the Ovi Store and Microsoft has promised Windows Marketplace for Mobile is on the horizon, so it's no wonder that Samsung didn't want to leave its fans out in the cold.
Omnia i900 users need to install the inventively named Samsung Application Store as an application, while i8910 HD users will get it after upgrading their OS. Either way, you should head to the store to get started.
As we'd expect of a new store, there aren't many apps available yet -- Samsung told us 300 are currently up for grabs. It promised that support for other Samsung phones will be coming soon.
We gave the store a whirl on our Omnia i900, and, once we got over our rage at having to use a stylus, it was a pretty painless experience. Click 'continue' to see the Application Store in action.
