I don't know, my current phone still works and I'm broke right now.
but I would have paid a fair bit if it was an option when I got my phone

I still miss when I had a BlackBerry even though it was shit for a lot of things
spent a hilarious amount of time on IRC with the world's shittiest IRC client and using the world's shittiest SSH client (major terminal emulation issues)
but being able to do that shit in like 2010 felt like magic (＾Д^)

upgrading to an android phone was great because the software selection didn't suck anymore
but it was shit because on screen keyboards are ass and I'm definitely slower than I was on the BlackBerry, even with autocomplete and shit (・∀・)
