I never thought I would be quite addicted to Pokemon from yesterday. The game is just pretty awesome even though I'll still be waiting for the trading, battle and other features coming soon. Anyway, I started playing Pokemon GO with just an iPod Touch 6 and have it piggy back my iPhone 4S's 4G. It surprisingly works and is decently accurate.
As for trainer level, I was able to reach level 5 all in one day from yesterday and currently caught 26 Pokemon. For the gym, I haven't encountered one yet but I'm probably thinking on joining Team Mystic out of the three teams. Feel free to check out my Twitter for Pokemon GO adventure updates. Will post more about the game later once I have more thoughts.
