We haven't had any ebook announcements for some time now, but while Tonya was enjoying some much deserved vacation, I stayed home to work on the TidBITS redesign and on getting these two iPhone books ready. It's becoming ever harder to resist the iPhone's siren song, especially with the price drop, but I still can't quite justify the monthly cost considering how little I use my cell phone. Luckily, the new iPod touch looks like an excellent way to dip my toes into the iPhone lake before it grows into an ocean. If you're like me, and considering an iPhone, or if you've already taken the plunge, check out these books for everything you need to know, including how to solve problems that crop up. Buy both and save 20 percent!
