Here is my solution to that. Don't use it all the time. Sounds stupid but it works.
I opened a second line with att for $10 extra. I have the iphone on one line and my SLVR L7 on the other. That way when I want some phone to run to the game and don't want to break my iphone I grab my SLVR. If I go to a seminar or out of town or to the store I grab my iphone. If I need web and ipod that is when I take it. Works out quit nice.
Oh sure great solution, just pay for 2 phone lines and two phones. pff.
