If AT&T‘s decision to cut the unlimited data plans to a finite amount has you jittery, fear not Virgin Mobile customers! You can rest at ease knowing that your “unlimited” plan is truly unlimited for just $40 every 30 days. If you are a frugal user of data on your cellphone, then you may still want to hang on to your $20 a month 300MB plan. But hardcore net addicts and perpetrators of extreme Facebooking will want to shell out the extra doe for an endless supply of data packets. Virgin Mobile users can make the choice August 24th.
