Because of the popularity the IT product from Apple has had in the last few days, IT companies O2 and Orange have started ordering a lot of micro SIM cards which are compatible with the iPad. The product is on everyone's lips because of the many interesting features it has and the fact that owners can use IT services like IT connectivity and surf the Internet on their iPads at any time and place. Interesting enough, nobody knew what a micro SIM was, that is, until this week, but it seems that this new concept may replace the old SIM cards. Apple is one of the first tech giants that has looked into this new format and manufactured it. The thing is that this is sure to be a new trend that will be adopted by other tech giants too. O2 and Orange have started to prepare for the UK launch of the iPad in its 3G version. Fans will be able to buy whatever version they want to when the product is released in the UK.
