Web, web and more web is the latest message from Sony Ericsson. The handset manufacturer has launched two HSDPA 3G handsets with the simple aim of getting more customers hooked on compulsive on-the-fly email checking.

Sony Ericsson's G502: 'super 3G' enabled

The G502 handset operates over tri-band GSM/GPRS/Edge, whilst the Z780 is a quad-band handset. Both are capable of UMTS 3G connections and HSDPA high-speed downloads to help bring “the power of the web to a mainstream audience”.

Both models come with Google Maps pre-installed, and the Z780 has the added benefit of Assisted GPS (AGPS) to compensate for weak satellite signals by sending data about your current location over your carrier’s network. AGPS already features on numerous handsets from other manufacturers, such as Nokia’s N82 and N96.

Two-megapixel cameras are built into both handsets, although the G502 has the more powerful 4x digital zoom. SE has set each model up for music funs too, with the inclusion of MP3 and AAC format support and the ability to stream music from either handset’s Memory Stick Micro storage card to another device over Bluetooth A2DP.

The Z780 will be available in either "Grand Onyx" or "Amethyst Silver" colours, while G502 fans can choose between "Champagne Black" or "Brilliant Hazel" shades. So far SE has only said that the two phones will be available in "selected markets" in Q2.
