Are 4G versions carrier locked?

No they are not carrier locked. You just need to know what 4G system you want to use your iPad on whether CDMA or GSM then buy that version iPad.

No iPads are ever locked. Just take in mind that CDMA and 4G use different frequency so u must consider a carrier u going to use.3G u can use in any network without limitations

hi dude, yes you can upgrade fron 4.0 to 4.1.2 Jb, here in my country the 3g works fine with all the bands and companies!

This is the international version. So no you aren't going to get all 4g LTE channels from T-Mobile.

No, you will need to go to the store for setting it up as the unlocked phone doesn't have the data settings. Also note this specific model is 3G only. If you want 4 G LTE then you need to get the 899 model.

Yes! This device is not locked to any specific carrier. I've personally tested it on T-Mobile's network and it works fine... but only in areas where T-Mobile has upgraded their network to support 4G on the frequencies this device covers.

Hello. I think all carriers as it is unlocked. I sent it overseas and it works perfect.

Yes, It is unlocked. You must put a Verizen 4g LTE MICRO SIM card in ($8-$10). Verizon did away with CDMA on 4G LTE phones.

It isn't locked to a particular carrier. I went with H20 cell service. I bought a SIM off ebay for about 10 cents and loaded it with a "pay by the minute" plan from H20. You can use any carrier that has a pay as you go plan.

It is not locked to a particular carrier. I was able to use it outside of the US, in the Caribbean area, with a non US carrier.

It's unlocked from all carriers. Simply put the GSM chip in and go. You may have to search for one that is tied to version.

Yes, the international version will probably not have 4G LTE service. You need to check with the carrier you are using to make sure.

Yes. We have 4g and we went from 2 bars to 5. Our first booster didn't work though, so if your phone doesn't connect, chances are it's a faulty tower.

No unlocked means it's not meant for a certain carrier you can use it with any carrier you want to go with or with out with no carrier

please confirm if in fact the iPhone 4 is never locked, if it can be used on any carrier around the world and if I can update it.

You will have to check with your local carrier but this phone does support most 4g carriers
