I have a Verizon I phone 4 there is no way I can delete apps if I hold my finger on an app for 30 seconds I still don't get no little x mark is my phone defective?
But then jailbreak is invoke which is not what the topic opener needed. I was thinking that maybe there was a restriction on deleting apps from the home screen. Well If it's about those inbuilt apps, you won't be able to get rid of them unless you agree to jailbreak and open ssh like Unleashed said.
