Option 1: iPad 2 Wifi + 4GB Data Plan on iPhone4 = $45/month for data vs. Option 2: iPad 2 3G + 250MB Data Plan + Unlimited Data on iPhone 4 = $45/month for data I currently have the precious Unlimited Data Plan on my iPhone 4 from AT&T, and will be getting my first iPad 2 very soon. Looking at both options above, I think I am going to relinquish my Unlimited Data Plan and give Option 1 a go! Reasons: 1. I will have my iPhone with me at all times, therefore, why not use it to tether the iPad. 2. My data usage on my iPhone has been, frankly below 2GB/month on average. Therefore, unlimited data hasn't been beneficial to me. 3. The 4GB Data Plan seems reasonable to be shared between both devices. I see myself using one device or the other (not both at the same time) for data usage. Therefore, if my iPhone data usage remains at or below 2GB/month on average, then that leaves 2GB or greater/month for the iPad (250MB just isn't going to cut it I feel). 4. Save $130 for the Wifi version and not be tied down to expiring 3G technology. If I go with option 1 (tethering). How is the data usage performance on the iPad? Is it a hassle to turn on/off tethering on the iPhone every time you want the iPad to use the iPhone's data? Your comments and suggestions are appreciated. Thanks in advance!
