Monster iPhone – Download | Unlock | Review

I only want to jailbreak it so I can get apps like in the app store and download stuff like that. I dont want to unlock it to get T-mobile service. I know you lose 3g speed if you use T-mobile sevice. So I wondering if the same thing happens if you jailbreak it

No, I doubt it, I have the iPhone 3G and have not had any trouble with loosing any speed at all after jailbreaking. I have been jailbreaking it since I first got it, never had any problems like that. If you’re worried, I suggest you use the latest and most uptodate jailbreaking tool, because the support you need will be available just in case you run into any problems. I’ve got a link attached for you which features the most up to date news on the jailbreaking tools that you need.
