I'm new to Android and just got my first Android phone yesterday... a NEXUS 5! 
1. Do I need to call my carrier (WIND Mobile) to let them know I'm using an Android phone in order for them to change the data plan? (APN settings, BIS data, etc) I just used the same SIM card from the Blackberry and everything seems to be working.
2. So many people are suggesting I unlock the bootloader... should I ?
