ATRIX 4G users rejoice - HSUPA will soon be here, and without any sort of hacky flashing requiring root access. The official Motorola update page for the ATRIX 4G's latest OTA, 4.1.83, has appeared on Motorola's website today. Here's the change log "highlights" according to Moto:
Increased speed at which data can travel on the network.
Improvements to prevent interruptions to data connection.
Improvements to prevent screen from freezing.
Improved ability for users to receive email notifications so you know when you have a new message. Also, improvements were made so that you are now able to use the same email login to access both MOTOBLUR™ and YouTube.
