[General Questions and Answers] poetryrocksalot:
Before you read this, question 4 is very long because I wanted to thoroughly describe my usage behavior. I just received a T-Mobile G2 on January 21, 2011.

Here are my questions regarding Android:

1. If I purchased an app on the "Market" will I be able to download the .apk version of the installer?

= = = = = = = = = =

2. I don't want to repurchase apps that I've already purchased. If I decided to change my Gmail "sync" account due to massive spam, would I still be able to transfer the software "license" to my new Gmail address?

= = = = = = = = = =

3. How do purchased and buyer-restricted apps get activated on a phone? Do these apps deal with "serial keys", or "evaluation keys", or "activation keys"...or do they only go by software licensing to a Gmail account? Or is there something else that I am missing?

= = = = = = = = = =

4. Is 200 megabyte-per-month data plan enough for me?

I often use 3rd party apps like: alarm clock, calendar, notes, system scheduler, Sprite Backup, music player, CorePlayer. I can't live without a good alarm clock, calendar, and notes app.

Once in awhile I use Shazam (1 song per month), Web (reading 1 out of 5 "unread" articles on Engadget and Gizmodo that interest me), RSS widgets (live feeds on home screen). I also want to Sync my Google Contacts and Calendar 24/7. I only check my school email or write email messages in times where I have no internet-able PC and where I am within a 1 day deadline to send an email to my professor. This happens about 5 times a month. I might use Web to look up answers for school problems and projects, but most of the time, a PC is in front of me, and it's more efficient to use the PC.

I rarely use apps like: Facebook, Twitter, YouTube, Stocks, Google Maps, Garmin, Pandora, internet radio, Yelp, etc...I go to the PC for these. But I admit that if I can afford unlimited data, I would definitely use internet radio apps including Pandora.

I do NOT want to use WiFi because I always need to provide "additional log-on" information which is basically entering a PW and a unique ID per log-on session. And no, I can not save the PW and ID into my browser settings.

To tell you the truth, I would buy non-smartphones if only they at-least came with a good built-in calendar, contacts, alarm clock, notes app, and physical keyboard. Staying organized is very important to me.

= = = = = = = = = =

5. I like to flash my ROM or update official ROMs without worrying about lost data. How reliable is Google Sync for Calendar and Contacts? Is it reliable enough that I do not need to purchase Sprite Backup?

= = = = = = = = = =

6. Is there any special way for me to make custom ringtones for the built-in clock and contacts app? I am talking about putting an MP3 into a "special" folder with a "specific name and location" or converting it into something like ".WAV" which could possibly the ringtone "format" for android.

I prefer not to install an Android app if there are workarounds like the ones I just mentioned.

I am ashamed that a crappy OS like Symbian can do it without any 3rd party reliance, while a pretty good OS like Android has this one built-in flaw. It's not like Nokia patented that right? I mean come on, if a 3rd party app or Nokia can do it, why can't a 1st party Android app do it?

Hope you guys can help me.

Thanks!
