If I was to get a new O2 sim card & register it on my Iphone (with a different number) & put £10 on it, could I then take it out & use it in my other phone (not an Iphone), & get the unlimited broadband for £7.50 a month.

Also, would my old O2 sim card still work ok back in my Iphone with the old number.

Cant see any reason why not, however i would have to ask the question why?

If its for the BTooth DUN setup, remember that its not dependent on the phone that you make the DUN call from; more where you make the DUN call too and the access credentials that you use.

If you're going to use the iPhone DUN details you could still get issues using it outside of the iPhone hardware/ software. (ie - additional charges etc - if you get my meaning!)
