Hello, Short of wanting to reinvent the wheel....I am in the USA on honeymoon. I have the opportunity to get the iPhone 5 "sim free". As many know, the A1429 model in the USA is a little different from that sold in the UK. I have been told the sim free "unlocked" handset in the USA is indeed a Verizon handset, which from what I see is unlocked out the box. My questions are: can I use the USA handset in the UK using EE's 4G or is it just gsm unlocked (and locked LTE)? And, with this US handset, will I be able to call and browse the internet simultaneously? Finally, without looking at the spec sheet, has anyone here actually done the above, and if so, may I ask of experiences please? Many many thanks for your help.
