Today's Mobile Minute brings you news about the relationship between consumers and telecoms in Sierra Leone, potential problems with mobile phones for transparency in elections, law enforcement officials pulling evidence from iPhones, how international roaming charges were dropped in East Africa, and why geotagging photos may not be in your best interest. 

• The third-annual meeting between consumers and Sierra Leone's National Telecommunication Commission happened last month, bringing together mobile users and telecoms to discuss the country's mobile service. 

• In "Elections, Mobile Phones and the Traditional Media," Hannah Brown looks at the hype around mobile phones and transparency for upcoming East African elections – and why mobile phones may not live up to that hype. 

• Information pulled from iPhones may be used in police investigations – everything from browsing histories to geotagged photos and GPS data can be searched and used as evidence in cases.

• The research paper "Regulatory Intervention or Disruptive Competition?" looks at how the creation of Celtel's (now Zain) One Network catalyzed telecom operators to drop international roaming charges in East African countries. 

• The International Computer Science Institute reports that photographs shared on social networking sites can "be used to reveal the geographical location of the people who post them."
