I sold off my MacBook as it started to get dated and rather clunky to carry around everywhere, and bought an iPad 3G instead. I activated on launch day and kept the $30 unlimited plan. Now that the iPhone 4 will reach the masses in a couple of weeks, AT&T decided to "lighten up" on the data plans, a $15 plan for a paltry 200MB. What if I kept my iPad 3G going on the $30 unlimited, jailbroke it for MyWi, and got the iPhone 4 with that smaller plan? For a total of $45 a month, one can use the iPad 3G as a mobile Wi-Fi hotspot, which beats the overpriced, separate monthly charge for tethering (which won't even work between the two devices), wireless data for both devices at will, and even FaceTime over that Wi-Fi hotspot. Apple & AT&T's way: iPhone 4 with $25/2GB + $20/tethering and iPad 3G for $25 to 30/2GB to unlimited = $65-70 just for data Ultimate Combo way: iPhone 4 with $15/200MB and iPad 3G for $30/unlimited = $45 for data + free hotspot + FaceTime, other "Wi-Fi only apps", 20MB+ iTunes/App Store downloads anywhere Not a bad idea, no?
