i am signing up for the free trial period of mobile me, whilst filling out the form it asks for your phone number and of course i am not sure if i should divulge this as i have an unlocked and jailbroken phone on t-mobile, would this matter.
Mobile Me needs some work, but it functions fairly well. The web app can be hit or miss. Sometimes it cannot find thing and other times you enter all your data for a contact or appointment and it refreshes and totally loses what you entered. So make sure it took it. The sync though is very fast!
What is still driving me crazy is why the gallery cannot be sorted alpha numberic? On the iPhone upload or on the web or in iphotos? It is such a pain trying to find particular albums!
