Hello guys, I was always against jailbreaking my iphone 4 because I thought it makes the iphone 4 too unstable, until I got an iPad and Rogers here in Canada wants to charge me an extra $20 to share my 6GB data plan! I want to be able to tether without paying $20! I just have some questions that I can't seem to find about jailbreaking! Will I still be able to buy apps and update them regularly on the iphone? As I only want to jailbreak to get MiWi lol Please let me know, thanks guys!!!
