This will happen when 2013 rolls around, and O2 predicts that it will offer double the Wi-Fi coverage compared to currently offered premium hotspots by BT OpenZone and The Cloud combined. The new Wi-Fi system roll out starts today, where O2 will first replace the 450 existing Cloud hotspots in O2′s retail and office operations. It will soon expand across various venues in the UK, where among them include retail outlets, shops, restaurants, as well as a bunch of indoor and outdoor locations across the country. With such news, any phone without Wi-Fi connectivity in the future will definitely not be worth its salt.
