Set on buying an iPad 2, but not sure whether you need the 3G version? Have an iPhone? Then maybe you can save $130, plus $15/$25 every month. Here's how.
Step 1) Follow these instructions on how to jailbreak your iPhone and create a Wi-Fi hotspot. It's not technically condoned by your provider, because they want you to pay an extra $20 a month for the purposes of tethering. You can read that last sentence as "they want you to pay an extra $20 a month for using data you've already paid for." Screw that. Do this instead, and pay only $20 once.
