I find the most effective way to obtain the information I want in the mobile environment is through 82ASK. It involves no graphics or Java downloads and is available on even the most basic mobile handsets. You simply text your question to 82275 (in the UK) and they send you back an answer.
Each question costs GBP 1.00 and it can take several minutes for an answer to arrive, but the experience is superior for several reasons. Firstly, the answer is almost always exactly what youre looking for and, secondly, the time delay is asynchronous. The interaction method of SMS is perfect for the mobile environment, because you can quickly input a question and then put your phone away and forget about it until it beeps to alert you to the answer. When you’re walking down a street or standing on a train, this is a much better way to request information than the synchronous continuity of the browser environment.
