At the moment i've got a iPod touch 2g, I've jail braked it and so far it shows no side effects-everything works fine.
I like the interface alot, so have considered getting a iphone 3g, BUT was wondering about the following factors;
Can you get free apps if you Jailbrake it?
Is the only way i can get 3g internet, to have a o2 sim?
Can you download new apple firmware updates if its Jailbraked?
Will it permanently void the warranty?
Are there any other bad side effects?
