It's been awhile since I've written about an accessory, but today something I recently acquired has totally saved my keister. It's the Kingston 1GB adapter pack - which is just a microSD card (1gb in this case) with an adapter to miniSD and standard SD.
Switching between phones is a huge hassle and it gets even bigger when you factor in a memory card swap. My preferred solution is to just keep everything on the smallest card possible and then use one of these adapters to plug it into whatever phone I'm using at the moment (or into my digital camera). One card means I know where my data is all the time and that makes me a happy camper.
