currently using a htc desire a8181,
feeling comfortable with it, but as time goes by it's kinda wasted, since it's 2 years old now.
i did not inform myself about new products so far, i just know i do not want to get an iphone.
am i able to use my current memory card (micro sd) on any other smartphone which is not an htc? am i able to copy everything i have on my recent one to the new, including apps, contacts and more?(dont wanna lose everything)
im very bad at those things, it might sound stupid but i just did not read myself into all that

(kinda lazy and did not have to, and there are just so many out there)
so basicly i just wanted to ask you guys about your experiences with the "newer" generation of smartphones,
and maybe give me a "pro tip" on what to get (just a name and/or serial so i can google it up or something, and why you would suggest it, are you using this by yourself?)
gonna use it for general things like phonecalls, surfing, fun apps and such. also the size of it matters a bit, since i do not wanna run arround with a "baseball bat" in my pocket =)
hope this is the right section for a thread like this
thanks in advance
