If you haven’t ordered it by now, it would be important for you to know that there are 3 different models to choose from. One GSM models and one CDMA + GSM combination.
The one that will work in Asia and Kuwait would be the A1429 GSM Model (+ future LTE compatibility maybe -the A1428 USA (GSM and LTE) would work on GSM but not maybe not LTE – future network to be available in Kuwait) ! However the only thing is that it is not clear how to differentiate between the two models when ordering, especially if you are ordering from the UK store.
I would recommend calling them up to verify that the model is the A1429 GSM version (not CDMA). I would also recommend waiting to hear more from the local carriers, as it would not be wise to invest in handsets that would not support the LTE network that would be available in the coming months in Kuwait (Hopefully).
I didn’t order it yet and decided to wait to try it out. Not ready to part with my HTC One X yet.
Price wise? Its not very wise to buy it from the UK apple store since you’ll be paying 100 GBP in VAT which i feel is too much and adds an extra 40 KD to the price of the phone. Is there any other store you tried buying from ? I hear Hong Kongs apple store are the cheapest, but we would need a HK mail forwarding company. Did anyone try buying from there?
