2 Mobile Gmail Accounts on Same Treo 650 Phone
2 Mobile Gmail Accounts on Same Phone
If you have two Gmail email accounts and want to access both via your mobile phone, Palm Treo 650 on Sprint in my case, follow instructions below.
The first step is to get a single account working. See post titled Google Gmail App on Treo 650 for how to get Gmail mobile for gmail.com or Google custom domains working on a Treo 650. The process should be similar for any phone that supports a Java Virtual Machine.
Once you have a single account working, adding a second account requires editing the Palm OS identification of the Java midlet so that Palm OS/Java Virtual Machine considers it to be a unique application and not an update or re-install of same application.
Midlet Name Change for Gmail.com Email
To change the midlet name the META-INF\MANIFEST.MF file in the .jar file will be modified. You will need to change midlet name, which identifies the application in the Java VM and then change the text after mdlet-1, which is the name of the installed application. See image below for edits I made to change name from “Gmail” to “Gmail 2″. BTW, I used WinRAR to open .jar archive and a text editor to make change. After you save the file and close text editor WinRAR will prompt to update archive file.

If you want to customize the icon you can update the archive with the desired GmailIcon.png file. The size should be 16×16 or 32×32.
Gmail.com Mobile 1.5 Email Midlets for Treo 650
You can either roll you own custom named midlets or use the files below that I have modified for five accounts. This midlet is only for gmail.com email addresses for Google App custom domain addresses follow the same process but start Google App Mobile Email midlet.
Download these via Java VM installer and accept install of application.

Excellent! works like a charm on the Palm Centro (GSM Unlocked version) with the IBM J9 VM 5.7.2.
I only need to find now how to change the security prefs so it NEVER asks me for permission to connect (it can be done for the Opera Mini browser, so I guess it’s possible too on this one).
Finally, it would be great if the app icon could be changed from the nondescriptive cube assigned apparently to all java apps.
Thanks for this!
