The latest xda operating system is now available. Benefits include:
Faster Internet access. Web surfing speeds increased by up to 33%.
An option for the GPRS call to be 'always on' even when the xda goes into power save mode.
Enhanced SIM management so that SIM entries are loaded into 'Contacts' as 'mobile' numbers, meaning texts can be sent straight from your contacts list.
An ISDN WAP capability for faster WAP access.
Be sure to not use this update in a non-O2 phone... Some of the configuration information is built-in the ROM, and your phone may lose access to the network if it's not an O2 XDA .
