I have 2 Inspires. Phone #1 is stock and set up for my daily work life. Phone #2 is rooted and I am just starting to play with Cyanogenmod 7. I want to switch between the phones when every by swapping the sim and sd cards between the phones. Phone #2 will be a playground for trying out different ROMs but I need phone #1 to be available as I cannot go without a phone during the work day.

Does anyone have any thoughts on what I should be aware of when I do this?
