I have 3G iphone with JB OS 3 b2
I have created custom carrier bundle with necessary instruction
I have symlinked to the corret carrier MCC/MNC number
Everything is working (like carrier Logo, MMS, thetering, etc)
Only problem is that APN settings inside carrier.plist are applied by iphone on SIM changing (physical change) not on ROAMING.
I mean that when a SIM is inserted in the iphone, all settings are taken from custom carrier bundle, and if I switch between two different carrier's SIM, all is OK, included APN setting that I found written inside the APN page of the iphone.
Problems start on ROAMING case, where the custom carrier bundle is partially well interpreted, with exclusion of APN settings, which remain that of original carrier (carrier provider of SIM card). No way to modify it on ROAMING case, even with Allow Prefix Matching or Type-mask in apn istruction inside carrier.plist.
Tks again for your help on this case :-)
