My current configuration is:
iPhone 1st Gen/2.5G running 1.1.4
Access to Windows XP/Vista or OSX 10.5 Leopard
1. What is the best/safest way to upgrade to 2.2 on my iPhone? I've heard people say "x is safer than y" when it comes to jailbreaking/upgrading a phone due to the different processes used - which is best and safest? Remember I have access to XP/Vista or Leopard.
2. I need to be able to absolutely control my prepaid data useage. I currently use BossPrefs as I know that turning "EDGE" off means that my iPhone will not use ANY data. I only use casual $1/day data very occasionally and don't want to pay "leaky" data usage. That's why I have not upgraded soon as I heard reports of 2.5G phones still being able to access mobile data even when the APN was set to an incorrect/dummy value.
Does the new 2.2 "set APN" feature mean that I'll be safe? Or if the value is "wrong" or a dummy value, will my prepaid mobile still access the GPRS network on my 1st Gen/2.5G phone on prepay?
