Hi, I'm visiting England in a few months and was planning on getting a data sim to use in my unlocked iPhone 4. I was looking at Three's network because they are the only ones that sell pre-loaded sim cards. I've seen that they sell pre-loaded mini-sims with 3GB and that looks to be a safe bet (after cutting it down). However, I saw that they also sell pre-loaded micro-sims for the iPad. These do not seem to be like the ones you have to put in an iPad to activate because they are more expensive and come pre-loaded. My question is, even though they say "for iPad", would I be able to get one to work in an iPhone (maybe by changing APN settings)? Thanks.
