Well, I wrote that 0x100039ce was the Unicode UID; it's instead the unique application UID (the one which Symbian centralized assignment). I found this "bug" while creating a new application from HelloWorld sources, and found that installing it on the P900 removed the original HelloWorld application. I will soon upgrade my site description. Another __very__ important thing: I definitively encourage you to write your own P900 & Linux tech experiences on the internet. Set up an home page, shoot a couple of weird P900 photos, place it somewhere with a "last updated on" note and add it to a number of search engines (if you are in a hurry). Let's exchange our links (I don't want to be the only source of information, neither the most complete source) and let Sony Ericsson see that Linux community is not as small as their commercial guys think. A P900 internet resource page is a serious source of useful information; while this mailing-list (as almost any other) is "googleable", it's quite hard to find out what one was searching for (because of quoting, questions, partial answers, etc). You don't have to be a "P900 guru", neither you need to be absolutely original, nor you need to cover any possible remote issue: just describe exactly how did you get something running, having in mind the user who just opened his brand new P900 package box. For this reason, I added a number of silly (oops) notes to let a new user proceed without too much fear between mysterious numbers and commands. alf
