Apple iPhone 3GS 16GB free on a $35 Rollover Cap Plan with Virgin
The plan includes:
$160 in talk & text
300MB Mobile Internet Data
Rollover Your Unused Credit
Unlimited mobile talk & text 24/7 to other Virgin Members
Plus your new Apple iPhone 3GS 16GB
I don't know if this applies to all types of Virgin stores but I can verify it is available at all TeleChoice stores.
This is a run out deal to remove old stock before the new iPhone.
There's no such thing as Jailbreaking an Android. Jailbreak means you circumvent Apple's security to run what you want off the phone but because Android is open-source and encourages development, you can do what you want. It just comes down to breaking Apple's restrictions.
Breaking a phone isn't illegal, but doing so to scam paid apps for free definitely is, and falls outside the 'Jailbreak' umbrella.
