Dalekkiller said:I got an iBGStar last year to use with my iPhone 4 and I really love it. I thought about upgrading my phone but Sanofi Aventis who make the meter said they couldn't guarantee the meter would work with the adaptor for the iPhone 5 so it might be an ide to check with them. The meters are quit expensive so do what I did and ask your DSN for one. I get test strips on prescription no problem.
