correct me if i am wrong. att ipcc update is for the att carrier so even if you update this on the iphone and are currently using tmobile the phone will work as if nothing happened. tmobile uses the VPN setting in sending out MMS. set that and you should be fine.
so technically tmobile users do not need to update the IPCC file. its no harm if they do though (just incase a att sim is ever used they can send MMS).
so the questions still remains use 5.5 or 6.0??
i hear that there is a 5.5 that is hacked for tethering and should be similiar to the 6.0.. can anyone confirm this?
Think the difference is 5.5 is MMS , 5.5 hacked is MMS and Teathering then 6.0 is MMS and teathering
