some guy in blackcointalk forum started to work on an android wallet and a lightweight client. If you want a mobile wallet donate to BQynghdBFW6RCcMXMgR2ys3yEkiVL77HK6 his target is just 1 BTC and with nearly 3000 received BC this is not so far away, please help him, you find his posts at http://blackcointalk.com/index.php/topic,1268.15.html . Help to make the android wallet true !!! just +4000 BC needed, more would be nice i think
