Thanks for using the forums! To see the status of upgrades in you area go to https://network.sprint.com/
Keep in mind, you CAN NOT move apps that are preinstalled by Sprint. Apps like Kindle, Adobe Reader, Adobe Flash, TeleNav, Nascar, etc.. that were installed as part of the OS have to stay on the mobile. The majority of all others can usually be moved to the SD Card.
Hopefully on future phones Sprint won't handicap us or the Android Developers will figure out a way to have the Updated versions of these apps move to SD Card. Time will tell.
I agree with the above about moving what you can to SD and moving or deleting your downloaded files. Thanks to some helpful people on here, I also found out that my internet cache, e-mail messages, and texts were taking up a large chunk of my memory. I didn't think I texted or e-mailed that often from my phone, but they apparently add up over time.
For your texting, it's best to set a limit regarding how many msgs to keep. You do this by going int othe messaging app and hitting Menu>Settings and looking for Storage Settings. Enable with a Checkbox and adjust how many SMS/MMS to keep per contact. I have mine set to 200/20
The truth of the matter is it's a major bug introduced with Gingerbread that HTC/Sprint are in no hurry to address. It's been reported thousands of times and we have been told that they were working on a fix, Then were told they are not. Chances are it will never be addressed. And all/any workarounds are temporary fixes as it will come back. Just search this forum and you will see how many are affected by it, And the conflicting information being provided concerning it.
a couple of apps that have for some reason been jumping in size are the email apps and for some reason the facebook apps. unless you actually use the facebook app go in (menu-settings-applications-manage applications-all) (once in hit menu again and then sort by size) and see which all apps are using ALOT of memory. if lets say facebook is using alot then chose that, go in and clear data and cache. actually i recomend doing this on apps you really dont use to gain more space back. unfortunatly this is a bug as levi pointed out. for some a factory reset fixed the problem. for others not so much. i was one of the lucky ones that the FR actually fixed it. just pay attention to the things youre going to clear though. also if you have pre installed apps in there that you obviously cant remove or ever use chose those and uninstall their updates. saves a bit more space right there.
