Hey all, So my 5S was recently blacklisted, etc, etc - that thread got detailed a bit BUT it's been sold and I have the trusty iPhone 4 to carry me until the iPhone 6 or whatever is announced. But the 5S has nano SIMs, compared to Micro in the 4 - besides buying a SIM converter, what can be done? Can I just walk into my T-Mobile store and ask for the right size? I do have a SIM activator kid, complete with micro SIM, from T-Mobile. Can I just use that SIM? Or is that only for new lines, etc? Thanks!
