If you activate your iPhone as a prepaid card or have an old SIM card the iPhone's behavior in terms of email and surfing the web through WIFI is still functional.
When extracting the SIM card with a paper clip by pushing one end into the top hole of the iPhone the SIM card pops out. You could only conclude that there must be an easy access to the SIM card and well there it is...
Now what is interesting is the SIM card in the picture at the bottom right has a 3G card?? Yet we are using the EDGE. This is an economy of scale issue. AT&T does not have the bandwidth in the 3G network to accommodate the demand.
AT&T's EDGE network does and so we have EDGE. I am not saying these are 3G phones but it is interesting to see a 3G logo on a SIM card!

Enough of the SIM card, once you have WIFI you have EMAIL, SAFARI and an IPOD! AN IPOD with EMAIL is still strong solution. It's just a matter of time before the hacks get to unlocking the services. When we see a UNIX shell this phone will be ready for SKYPE.. An this is the problem for AT&T and other carriers. here comes the technology.
The Cellosaur makes way for the TheroPODS (The IPHONES). Earlier in the week Mr Williamson sent me the notification of the SKYPE upgrade for the N800 devices.
