hi robin
with factory unlock i phone you can use any gsm carrier or Sim card provider, there is no problem with that. and if you update it's applications or upgrade it. it will never lock. but make sure your i phone must be factory unlocked. i used a factory unlocked i phone 4. so i can assure that. and i bought it from myworldphone it really work . and you can get your i phone with discount price from myworldphone.
