Any one know of anywhere such a tutorial exists?? Im trying to make a (mobile device) calculator/info storing program that would kind of be like quickbooks for soapmaker's where they can input a recipe and get calculated weights and measures and total batch stats, which can also be linked to the desktop version of the program... looking for some direction, what language?? php/javascript/mysql? asp.net? not sure which one to research as I dont know the real differences in them when it pertains to mobile devices... thanks for the help!
If you are writing for Java based mobile devices you can use J2ME. If Windows Mobile, you can use, C# with Windows Mobile SDK. See this nice Windows Mobile development guide.
