I'm not exactly the professional with the Blackberry yet...However, I do have a working HTML Browser on my Nextel 7250. When you download the 4.0 update from the blackberry.com website you do not recieve the HTML browser. However, you can a trial version from ReqWireless. If you have the Nextel version of the Blackberry you have to use the corp. edition because the nextel platform of the phone was built for the business user. To put the browser on your BB you download the .zip file and extract it to your pc. Next, you simply load it as you would any other .alx file. Since it is only a trail version you can only use it so many times a day for ten days. To buy it ou have to go to their website
www.reqwireless.com, it only cost a one time fee of 29.99. So far this is the only HTML version browser that I have tested, and so far i'm pleased with the results. The browser gives me the ability to both complete credit checks and phone sales from out in the field without having to go back to my desktop pc or my laptop. Some ppl may have to do as I did and call Nextel Data support and have them send you a copy of the Blackberry Browser Service Book. If you have any questions about this just shoot me an email on my blackberry, i'll be out of the office til late tomorrow night, so i'll help everyone the best I can from my blackberry.
