Normally you dial ##3282# and go edit the MMSC URL to http://mm.myboostmobile.com but everytime I dial that it says connection error, so how can I achive that or fix it? Everything else is working great, internet, phone calls and texting...

Also how can I install apps? I tried uploading them to my own personal and downloading the url, but that didn't work...

Then lastly how can I import my contacts from an xml or txt file? I've been reading about exporting them in outlook to csv and then importing them to a gmail account.
