Of course, the iPhone does so much more than surf the web. So, let’s open iTunes, Mail, and address book. iTunes (playing a song in “coverflow” mode, uses 40.44 MB of RAM and 258. 68 MB of Virtual Memory. Mail and Address Book come in at 20.59 MB/237.64 MB and 9.47 MB/171.39 MB respectively. Let’s add that to our previous total, using the calculator widget (something the iPhone supports, and which uses up another 7.43/163.43MB) and we come to 223.23 MB of actual RAM, and 1.83 GB of Virtual Memory.
That’s quite a lot of memory, and we haven’t even made a phone call yet!
