Even the most mobile Londoner gets lost once in a while and out comes the pocket A-Z to avoid embarrassment, but that's not exactly techie or even remotely gadgets like , now of course you could have something like pocket streets on your PDA but its a bit geeky to take a PDA out clubbing so how about having maps on your phone?

Tube London Streets for the P800 and P900 is just that the engine for this software suite runs on a P800 or P900 from Sony Ericsson, the name "tube" relates to the primary product a London Tube map which is good but as every train and station has a tube map we are at a bit of a loss as to why you'd but it, alternately the tube London streets application is far more useful.

So what is this software application all about, Tube London Streets offers a search facility with the main central London maps, input a street name and then select from the list the correct map will then be displayed on your phone which you can zoom into street level and then back out to gain a wider view of the surrounding area, the maps are broken into 9 tiles. Each tile at approx 1.5mb and they reach from Walthamstow in the NE to Chelsea in the SW, you can also search for points of interest like Tube stations, hospitals and general area like "Piccadilly".

Control of the maps is via the stylish and screen, you can scroll the map smoothly around each tile to follow your route, you can also specify a home location which may be your office , home or local station. The main Tube application takes 3.5mb of space on your machine and each of the 9 tiles are 1.5mb each, Tube London streets can be installed on the memory stick duo included with the P800 / 900 although you may want to get a slightly bigger memory stick if you want all the tiles (which we recommend).

On test we found this little application to be so valuable, the tiles are actually provided by the A-Z company so the data is spot on, its just the ticket for finding that little back street in Soho that you can never find first time, perhaps you might want to combine London Streets and the main Tube Pro application we guess it depends on need and finances. At £25 for all 9 tiles and the "tube" application its not the cheapest of applications but its certainly functional and a great gadgets to impress colleagues and customers.

While we reviewed the P800 / P900 version you can now also get Pocket PC / Palm and Smartphone versions.
