I just got the new GXP2140 again today and with the new firmware your not just able to sync your mobile phones but you can also change the logos and wallpaper. I looked around and did not find the sizes that the images need to be and after i finally found tehm i see that lot of people had issues with adjusting the logo correctly.
i took the time and prepared to templates in photoshop with this templates you can easily add / remove your logo, change the backdrop and never have to worry that your logo or your wallpaper will not fit with the grandstream phones, with teh generator they always do!
