iPhone 4 S

The book I read to research this post was iPhone 4 S for Dummies by Bob le Vitus et al which is an excellent book which I bought from Kindle. This is the smartphone I have & this book covers pretty much covers all you could possibly want to know about the iPhone 4 S. You can do video calls with it using Facetime & that also supports more than 2 callers at the same time or conference calls. It has a bigger screen than any of the previous iPods. It's essentially an iPod with phone capability. You should take it out of its case to recharge it as it can get quite hot which can damage the battery. If you install Skype on an iPod Touch you can make phone calls via a computer network. One of the best features of the 4S is the maps which work like a GPS & show you your location in relation to everything else. A lot of people want to use iCloud which is the current version of Mobile Me mainly instant messaging. To use that if you have a pc you need a minimum of Windows Vista with Service Pack 2 installed. You sometimes need to download updates or reset your iPhone via computer ie if it's malfunctioning. To do that if you have a pc you need a minimum of Windows XP with Service Pack 3. Apple will continue providing updates for the iPhone & one thing it said in the book is that might include support for video & audio formats that aren't currently supported. Certainly most of the major formats are supported. iTunes is quite nifty & you can download television shows, films, podcasts, music & apps for your iPhone from this. It supports the playback of video files in a HD format but these take up extra space on the hard drive. I think the podcasts are particularly good value as practically all of them are free.
