Hello everyone I have a 16gb iPhone 4S, and I'm wondering if I should jailbreak. Now, I love the idea of themes and tweaks, but I'm worried that Telstra (I'm in Australia, and they are my plan providers) will be able to see the jailbreak. Is there anything that would render my plan useless? Ive jail broken my iTouch before, I'm just a bit worried as my dad still pays for my plan, (it's under his name, don't ask) will be able to see the jailbreak. Oh and one more question, if I'm sending a iMessage from my phone number to a Apple ID, will they (Telstra) see that on my phone bill? Thank you so much!
